Key Takeaways
- Prosthesis providers can’t just enroll with payers. They need DMEPOS accreditation from a CMS-approved organization before they can even obtain Medicare billing privileges.
- Credex Healthcare ranks first among prostheses medical credentialing companies for coordinating accreditation, NSC enrollment, and payer credentialing as a single integrated process rather than 3 separate tasks.
- A $50,000 surety bond is required per NPI for most DMEPOS suppliers, and this requirement is often missed or mistimed by generalist credentialing vendors.
- CMS withdrew its approval of BOC as a DMEPOS accreditation organization in December 2025, a change that’s still working through legal challenges and worth confirming before choosing an accrediting body.
- ABC (American Board for Certification in Orthotics, Prosthetics & Pedorthics) and ACHC remain the two most commonly used accreditors for custom prosthetic and orthotic devices.
- Getting the sequence wrong and enrolling with payers before accreditation is finalized is one of the most common and costly errors in this specialty.
It’s not like getting credentials for most other specialties when it comes to prosthetics and orthotics. Many providers get stuck when they try to treat it like getting credentials for doctors. Even if a prosthetist has all the necessary clinical certifications, they still can’t bill Medicare for anything because they don’t have a license. The separate CMS requirement is DMEPOS approval, which most general licensing companies either don’t fully understand or treat as an afterthought.
If you’re starting a new O&P practice, adding a location, or trying to figure out why your Medicare enrollment application keeps getting held up, this guide will show you what you need to do and which medical licensing companies are good at it.
It should be made clear from the start that this isn’t something that a general medical billing company, even one that is good at verifying doctors’ credentials, can just add to their normal repertoire of services. DMEPOS approval has its own set of rules, accepted organizations, paperwork requirements, and a way to impose them through the companies that took over from the National Supplier Clearinghouse. A vendor who doesn’t know that track record will probably find the same holes in the system the practice does: after an application stops working.
Why This Specialty Breaks the Standard Credentialing Playbook
Most credentialing guides assume a linear path: get qualified, get an NPI, apply to carriers, and get accepted. With prosthetics and braces, you must take an extra step before any of that can pay off.
Under 42 CFR 424.57, DMEPOS sellers must obtain approval from a CMS-approved group before billing Medicare Part B. This includes providers of custom-made and custom-fitted orthoses, prosthetic devices, and external breast prosthetics. If you skip this step or put them in the wrong order, you won’t be able to enroll in Medicare, no matter how full the rest of your application is.
Another surprise for new suppliers is the need for a surety bond. DMEPOS sellers that must follow the bonding rule must provide the National Supplier Clearinghouse’s new agents with a $50,000 guarantee bond for each NPI. A supplier with twenty locations, each needing its own NPI, needs bonding that can be scaled up or down as needed. A seller can’t figure this out later. It needs to be planned before the applications are sent out.
DMEPOS suppliers must meet facility standards that most doctor practices don’t think about: they must have a physical business location with posted hours and no P.O. boxes. There are no virtual practices, no mailboxes, and regular, sometimes unexpected site checks are expected. Someone who hasn’t done an NSC site visit with a client before will miss things that someone with more experience would see.
Choosing a Credentialing Organization
CMS currently accepts several credentialing organizations for DMEPOS. The two most important for prosthetics and orthotics companies are ABC (American Board for Certification in Orthotics, Prosthetics, and Pedrotti’s) and ACHC (Accreditation Commission for Health Care). Both have been cleared for Appendix C, which is for custom-made and custom-fitted orthoses, prosthetic devices, and external breast implants.
Because it was designed with braces and prosthetics in mind, ABC is more likely to work well with companies that focus on those services than with general DME providers. In addition to prosthetic and orthotic services, ACHC covers a wider range of DME categories, which is good for providers that also offer items not covered by O&P, such as breathing tools or mobility devices.
Important to note: In December 2025, CMS stopped approving BOC (Board of Certification/Accreditation International) as a DMEPOS credentialing body. BOC sued to challenge the ruling, and as of mid-2026, the case was still in federal court. If a provider is already certified through BOC or is considering it, they should check their status directly with CMS before using it for a new application or refreshing an existing one.
What Accreditation Actually Requires
When providers are new to DMEPOS, they often think that accreditation is just a formality with a form to fill out and a fee to pay. It’s not. Accrediting groups ensure a supplier meets CMS quality standards. These standards cover a wide range of areas, such as staff qualifications, infection control procedures, equipment maintenance logs, and systems for keeping track of patient complaints.
For a prosthetics or orthotics practice, this usually means written rules for how to take new patients and fit them, proof that the people who make the devices are licensed or certified, a way to keep track of device warranties and follow-up care, and clear records that show how patient records are kept and kept safe. Nothing about this is strange. These things are already done by most well-run O&P firms. The work is writing them down in a way an accrediting body wants to see them, which is usually more formal and specific than how a practice normally works.
Because this is where a skilled certification partner makes money, if you don’t know what ACHC or ABC surveyors are looking for, starting from scratch with the documentation package can turn a simple accreditation review into a months-long back-and-forth. If your partner has been through the process more than once, they know which gaps get flagged most often and can help your practice close them before you submit, instead of after you get turned down.
How Site Inspections Work
Once credentialing is granted, it isn’t a one-time event. CMS will be doing annual accreditation surveys starting in 2026, which is stricter oversight than in previous years. This means that DMEPOS suppliers, such as prosthetics and orthotics practices, should expect ongoing, sometimes unannounced site visits instead of just one initial review.
Inspectors usually check that the business is located in the same place as what is listed, that the stated business hours are correct and that the location is actually filled during those hours, that the business has professional, easy-to-read signs, and isn’t running out of a P.O. box or a home address that looks like a business location. If a practice has more than one location, each one needs to meet these standards on its own. One location that doesn’t follow the rules can lose its ability to bill, even if all the other locations in the network do.
Instead of rushing around before an inspection, businesses that treat this as a regular compliance duty and include it in routine internal reviews tend to handle these visits with a lot less trouble. It’s better to have a credentialing partner who lets you know about upcoming survey windows and helps you do a practice self-audit ahead of time than one who only acts after you get cited.
What the Best Prostheses Medical Credentialing Companies Actually Do
For this specialty, a good credentialing partner must handle four things at once: the security bond, NSC enrollment, time of accreditation, and payer credentialing. These must be handled in the right order so nothing blocks the next step.
Here’s how the field compares.
Credex Healthcare
Credex Healthcare is at the top of this list because it sees DMEPOS approval as the first step in the process, not an extra task. The team works directly with accrediting bodies like ACHC and ABC to make sure that all the necessary paperwork is ready to be sent in. They also keep track of the bonding requirements by NPI so a provider with multiple locations doesn’t end up without enough insurance. Finally, they don’t start enrolling payers until accreditation is confirmed and everything is going through the right NSC channels.
For prosthetics and orthotics practices in particular, this sequencing discipline can mean the difference between getting Medicare reimbursement in six months or more than a year because an application was turned down for lack of proof of accreditation. Credex also prepares clients for the facility standards and site visits that come with being a DMEPOS supplier. This is something newer or more generalist vendors often don’t do until a client is caught off guard by an inspection.
The prices are clear for each site, and the work involved in coordinating approval isn’t hidden in a vague line item called “credentialing services.”
DoctorsManagement
DoctorsManagement has a background in consulting, which can be very helpful for O&P practices getting accredited for the first time, especially when it comes to meeting facility standards and preparing for site inspections. Cost is the trade-off. Their all-inclusive advising model is usually more expensive than companies that only offer licensing as a separate service. This might not work for smaller, one-location prosthetics businesses that are trying to make ends meet.
MediBillMD
MediBillMD’s approach to bundling bills and authorization can work for smaller O&P practices that want to handle fewer vendor relationships. The licensing side isn’t very good at coordinating DMEPOS accreditation, so practices should check directly with the credentialing group to see if accreditation of contact work is part of the job or if it needs to be done separately.
CredentialMy
CredentialMy’s lower-cost plan is good for solo prosthetists and small groups, but the lack of help is most noticeable in a field with so many procedures. The DMEPOS accreditation sequencing team has a lot of experience because they’ve done it many times before. A younger, smaller seller may still be getting stronger.
Capline Healthcare Management
Capline handles a lot of credentialing quickly and efficiently, which works well for larger O&P groups with multiple locations that need to handle standard payer applications quickly. The part about coordinating approval is where it’s less proven. Instead of assuming it’s part of their general licensing services, practices should ask directly how often they’ve prepared ACHC or ABC approval paperwork.
PayrHealth
PayrHealth is good at negotiating with payers, so they can help O&P practices secure better payment rates once they are accredited and credentialed. This is a real benefit for practices that want to do more than just register. It works better as a second-stage partner, after the initial enrollment and accreditation are taken care of, rather than as the main vendor starting from scratch with the DMEPOS accreditation process.

A Real-World Scenario
A regional prosthetics company that grew from one location to three ran into a problem that happened so often that it was almost easy to see coming. Their old credentialing provider sent Medicare applications for the two new locations before either site had been fully accredited. Both applications were turned down right away, without being stalled, because DMEPOS billing powers cannot be given without proof of licensing status on file.
The provider lost about ten weeks redoing the process in the right order: first, they had to make sure that each new address was still ACHC-accredited; then, they had to get the necessary $50,000 safety bond for each new NPI; and finally, they had to resend Medicare enrolment thru the right DMEPOS contractor. The delay from the original expansion plan is just over four months.
If everything is done in the right order from the start, accreditation is confirmed first, bonds are secured second, and payer enrolment starts third, that same three-location expansion can be completed in five to six months. The order isn’t a small thing here. It’s the whole process.
Any O&P practice that wants to grow can learn something from that timeline. Accreditation is not quick, and neither is bond funding. Both need weeks of extra time, or longer if a governing body’s study schedule is full. People who start talking about licensing as soon as a new site is signed, instead of after construction or buildout is done, always meet their deadlines more quickly and reliably than people who wait until the very end, right before opening day.
Before we compare vendors, one more thing needs to be brought up: prosthetics and orthotics practices sometimes think their state DME license covers everything they need. It doesn’t. State license and federal DMEPOS approval are two different standards that must be met on different dates and by different groups. Having one does not mean you have both.
A practice may have all its state licenses, but it may still be months before it can bill Medicare because accreditation hasn’t been cleared. A step that should be built into any growth plan from the start is to confirm both tracks separately, rather than assume that state approval means federal approval is ready.
Frequently Asked Questions
Do prosthetics providers need DMEPOS accreditation before Medicare enrollment?
Yes. Before DMEPOS providers, such as those that make custom prosthetic and orthotic devices, can bill Medicare Part B, they must obtain accreditation from a CMS-approved organization.
How much is the surety bond requirement for DMEPOS suppliers?
In most cases, $50,000 per NPI. If a service has more than one office, and each one needs its own NPI, the agreement needs to be scaled to fit.
Which accrediting organizations cover prosthetics and orthotics?
The two most popular are ACHC and ABC. Both are allowed by CMS’s Appendix C category for custom-made and custom-fitted orthoses and artificial devices.
What happened with BOC accreditation?
In December 2025, CMS took away BOC’s license as a DMEPOS credentialing body. BOC went to federal court to challenge the decision, and providers should check the current situation before relying on it.
Can a provider start billing Medicare while accreditation is still in process?
Not at all. When enrolment forms are sent in before approval is confirmed, they are usually turned down right away instead of being held up. This is why it’s so important to do things in the right order from the start.
How does DMEPOS accreditation differ from standard payer credentialing?
Standard payer credentialing checks a provider’s background, training, and license. DMEPOS certification ensures the supplier’s business, facility, and operating practices meet CMS quality standards. This process must be completed before the supplier can be enrolled in Medicare.
Getting the Sequence Right from Day One
The prostheses medical credentialing companies worth hiring know that accreditation isn’t just extra paperwork that comes with credentialing. Everything else must go through this gate first. Credex Healthcare builds its O&P work on this fact, ensuring approval, bonding, and insurer enrollment happen at the same time so there aren’t three separate problems.
Fixing an application that was turned down after the fact takes months more time than getting approval, bonding, and customer enrollment done right the first time. Get in touch with Credex Healthcare to learn more about getting your prosthetics or orthotics practice DMEPOS accreditation and credentialing.
